IrDA infrared communication module
RPM872-H14
RPM872-H14 is an infrared communication module for IrDA Ver. 1.2 (Low Power). The infrared LED, PIN photo diode,
and waveform shaping LSI are all integrated into one single package. This module is designed for low power
consumption. The very small package makes it a perfect fit for mobile devices.
zFeatures
1) Applied to IrDA Ver. 1.2. (Low Power)
2) Designed for low power consumption at waiting mode (75µA).
3) Low operating voltage
